My suspicions too, Jeff.  I've seen the "do you want to rate up" window pop-up, but I always click on no.

I'm guess folks click on yes, then these glowing reviews show up.  And they are SO, SO helpful in dealing with program issues and/or tax issues.

I may click on 'yes'  the next time the inquiry comes up and respond in a less-complimentary fashion to see if my post appears.   I'm taking bets on it if anyone wants to chime in.
